The biggest difference between bearing steel and thin-walled steel pipe wall thickness is, in general, are cold-drawn thin-walled steel technology, while bearing steel typically use hot-swap technology, if it is used to distinguish between the unit of measure, then, is generally believed wall thickness / diameter equal to 0.02 was a watershed bearing steel and thin-walled steel pipe wall thickness / diameter less than 0.02, thin-walled steel pipe, is greater than the bearing steel, the purpose, the thin-walled steel used for the pipeline. The more used bad material bearing steel hollow parts, the use of pressure and important pipeline.
